Bargraph Board

Here is my most complex design so far: our bargraph board. It includes 8 TLC5954 to drive 128 RGB LEDs (384 LEDs in total), a DRV8837 to drive a motorized fader, an ATmega328 to control the LED drivers, motor drivers, and 3 illuminated switches, and an FT232RL to provide a USB interface. All this will need to fit on a 13 × 150 mm board, which won’t be easy but should be doable with careful component placement.
